Hi,
I was hoping someone can point me in the right direction.
in my app i need to be able to connect to other accounts so i have
implemented oauth2flow which i took from the example app.
it lets me log in to an account just fine and i get the oath object back. I
can also make a call to the campaign service with no errors returned but
the campaign page object always returns with no entries.
i don't think its permission thing because when i run the example app i
get my test accounts back.
i just wish i had an error to work with
below is my code:
Base controller: (used to store the oauth object between controllers)
public class BaseController : Controller
{
protected internal static HttpSessionStateBase MySession { get;
set; }
protected internal static OAuth2ProviderForApplications OAuth {
get; set; }
}
Auth controller:
[HttpPost]
public ActionResult AuthUser()
{
var config = _user.Config as AdWordsAppConfig;
if (_user.Config.OAuth2Mode == OAuth2Flow.APPLICATION &&
string.IsNullOrEmpty(config.OAuth2RefreshToken))
{
return RedirectToAction("AuthLogin");
}
//TODO: need to add error page
return RedirectToAction("Index");
}
public ActionResult AuthLogin()
{
AdWordsAppConfig config = new AdWordsAppConfig();
if (config.OAuth2Mode == OAuth2Flow.APPLICATION &&
string.IsNullOrEmpty(config.OAuth2RefreshToken))
{
DoAuth2Configuration(config);
}
return RedirectToAction("Index");
}
private void DoAuth2Configuration(AdWordsAppConfig config)
{
// Since we use this page for OAuth callback also, we set the
callback
// url as the current page. For a non-web application, this
will be null.
config.OAuth2RedirectUri =
Request.Url.GetLeftPart(UriPartial.Path);
// Create an OAuth2 object for handling OAuth2 flow.
OAuth2ProviderForApplications oAuth = new
OAuth2ProviderForApplications(config);
if (Request.Params["state"] == null)
{
// This is the first time this page is being loaded.
// Set the state variable to any value that helps you
recognize
// when this url will be called by the OAuth2 server.
oAuth.State = "callback";
// Create an authorization url and redirect the user to
that page.
Response.Redirect(oAuth.GetAuthorizationUrl());
}
else if (Request.Params["state"] == "callback")
{
// This page was loaded because OAuth server did a callback.
// Retrieve the authorization code from the url and use it
to fetch
// the access token. This call will also fetch the refresh
token if
// your mode is offline.
oAuth.FetchAccessAndRefreshTokens(Request.Params["code"]);
// Save the OAuth2 provider for future use. If you wish to
save only
// the values and restore the object later, then save
// oAuth.RefreshToken, oAuth.AccessToken, oAuth.UpdatedOn
and
// oAuth.ExpiresIn.
//
// You can later restore the values as
// AdWordsUser user = new AdWordsUser();
// user.Config.OAuth2Mode = OAuth2Flow.APPLICATION;
// OAuth2ProviderForApplications oAuth =
// (user.OAuthProvider as
OAuth2ProviderForApplications);
// oAuth.RefreshToken = xxx;
// oAuth.AccessToken = xxx;
// oAuth.UpdatedOn = xxx;
// oAuth.ExpiresIn = xxx;
//
// Note that only oAuth.RefreshToken is mandatory. If you
leave
// oAuth.AccessToken as empty, or if oAuth.UpdatedOn +
oAuth.ExpiresIn
// is in the past, the access token will be refreshed by
the library.
// You can listen to this event as
//
// oAuth.OnOAuthTokensObtained += delegate(AdsOAuthProvider
provider) {
// OAuth2ProviderForApplications oAuth =
// (provider as OAuth2ProviderForApplications);
// // Save oAuth.RefreshToken, oAuth.AccessToken,
oAuth.UpdatedOn and
// // oAuth.ExpiresIn.
//};
Session["OAuthProvider"] = oAuth;
OAuth = oAuth;
var t = Session["OAuthProvider"];
// Redirect the user to the main page.
Response.Redirect("Index");
}
else
{
throw new Exception("Unknown state for OAuth callback.");
